AI Technical Summary

Benefits of technology

Effectively prevents terminal fittings from being inserted in improper postures by increasing the interference when an improper posture is detected, ensuring correct orientation and simplifying the inner wall shape of the terminal accommodation chamber.

Problems solved by technology

The stabilizer interferes with an opening edge of the terminal accommodation chamber if the terminal fitting is attempted to be inserted into the terminal accommodation chamber in a vertically or laterally inverted improper posture.
Thus, a degree of interference of the terminal fitting with the housing increases.

Embodiment Construction

[0018]An embodiment of the invention is described with reference to FIGS. 1 to 9. In the following description, a left side in FIG. 1 is defined as a front concerning a front-rear direction. Upper and lower sides shown in FIGS. 1 to 6 are defined as upper and lower sides concerning a vertical direction. Left and right sides shown in FIGS. 2 to 6 are defined as left and right sides concerning a lateral direction.

[0019]

[0020]A connector of this embodiment includes the housing 10 and terminal fittings 30 and are mounted into the housing 10 from behind. The connector has a waterproof function and a function of detecting an improper posture when the terminal fitting 30 is going to be mounted into the housing 10 in a vertically inverted improper posture.

Abstract

A connector includes a housing (10) formed with a terminal accommodation chamber (13) and a terminal fitting (30) to be inserted into the terminal accommodation chamber (13) from behind the housing (10). A stabilizer (35) projects from an outer peripheral surface of the terminal fitting (30), and an interfering portion (19) is formed on an inner wall of the terminal accommodation chamber (13). The terminal fitting (30) contacts the interfering portion (19) when the terminal fitting (30) is inserted into the terminal accommodation chamber (13) in an improper posture, and this contact presses the terminal fitting 30 in a direction intersecting a projecting direction of the stabilizer (35).

Description

BACKGROUNDField of the Invention[0001]The invention relates to a connector.Related Art[0002]Japanese Unexamined Patent Publication No. 2016-062807 discloses a terminal fitting formed with a plate-like stabilizer projecting on an outer periphery. This terminal fitting is inserted into a terminal accommodation chamber formed in a connector housing. A guide groove for accommodating the stabilizer when the terminal fitting is inserted in a proper posture is formed in the terminal accommodation chamber. The stabilizer interferes with an opening edge of the terminal accommodation chamber if the terminal fitting is attempted to be inserted into the terminal accommodation chamber in a vertically or laterally inverted improper posture. Thus, the insertion of the terminal fitting is restricted. Specifically, the stabilizer has a function of detecting whether or not the inserting posture of the terminal fitting into the terminal accommodation chamber is proper.[0003]Some known terminal fitting...
